II. licvoLUCRE (feo/wcrwm), is a calyx remote from 
the flower, — most commonly stationed' at the 
foot of a general, or partial, umbel. 
III. Spathe {Spatha), a species of calyx, which first 
involves the infant flowers like a sheath, and 
then opens longitudinally. 
IV. Glume {Gluma), the outer valves, or husks of 
corn, or grass, enclosing one, or more, florets. 
y. Ament {Amentum)^ small chaffy scales, protect- 
ing the florets placed on a thread-like common 
receptacle. 
VI. Calyptra (Cahiptra), the covering of a moss, 
placed over it, like a cap or bonnet. 
VII. VoLVE (Folm), a membrane, which involves the 
fungus in its infant state, and which afterwards 
appears in a lacerated form on the foot stalk. 
N. B. The Calyx, like other green bodies, possesses 
a power of secreting from its surface J^ital or 0.vygen 
Gas, whereas, when coloured, like the painted corolla, 
it then deteriorates the atmosphere, imbibing within itself 
the vital air, giving out azotic gas, as does also fruit. 
* Most coramonly stationed) not always, as in Anemony and Passion- 
Flovser^ a somewhat rare occurrence. 
^ A general and partial Umbel) Umbelliferous, or Umbel-bearing 
plants, are of two kinds; from a common centre proceed the peduncles, 
or flower stalks, like the sticks of an umbrella, and when each pe- 
duncle terminates with a flower, as the Geranium^ Cozzslip^ Meadia^ 
the Umbel is then called general ; but if these peduncles, instead of 
terminating in a flower, end in a fulcrum, or point, whence other pe- 
duncles proceed, and these terminate each in a flower, the Umbel is 
th en called partial ; and hence the involucre itself is called 2i general 
ov partial involucre. FooVs Parsley is an example of this last kind.
